RELATED APPLICATIONS

The present application is a continuation- of application Ser. No. 09/550,991, filed Apr. 17, 2000 now U.S. Pat. No. 6,775,562 and assigned to the same assignee as the present application.

FIELD OF THE INVENTION

The present invention relates to communication systems and more particularly to a remote battery replacement notification system and method.

BACKGROUND OF THE INVENTION

In the future telecommunication services that have traditionally been delivered by cable will be delivered by fiber optics or wireless channels. Fiber optics and wireless channels are not designed to carry power as Plain Old Telephone Service (POTS) does presently. As a result, subscriber units at a customer's location may be locally powered with battery back-up. The battery back-up will maintain continuous service of the telecommunication services during a commercial power failure. The batteries have a long but finite lifetime and the customer may not remember to check their batteries. Failure to replace the batteries will result in the customer losing their telecommunication services during power outage.

Thus there exist a need for a battery replacement notification system and method.

FIG. 5 is a flow chart of the steps used in a remote battery replacement notification method in accordance with one embodiment of the invention. The process starts, step 150, by polling a subscriber unit for a battery state by a communication system at step 152. A response is received that contains the battery state at step 154. When the battery state indicates that a battery requires replacement at step 156, a battery replacement notification is sent to the subscriber unit which ends the process at step 158. In one embodiment, the communication system receives a reply from the subscriber. When the reply is to purchase a new battery at a designated store, a battery discount is generated for inclusion in a subscriber's bill. The battery discount provides the customer a discounted price for the battery at designated stores. In one embodiment, the system notifies the subscriber of the address of the designated store. When the reply is to send a new battery, an order is transmitted to a battery supplier. When the reply is to install a new battery, the order is transmitted to a battery installation service organization. When the reply is to speak with a service representative, a phone connection is established with a service representative.

In one embodiment, a replace battery message is sent to a compact service node. Next it is determined when a subscriber has finished dialing a called number. When the subscriber has finished dialing a called number, the subscriber is provided with a plurality of battery replacement options. A response is received from the subscriber. A report reminding the customer to change the battery is sent to the billing system.

In one embodiment, the system determines a subscriber email address. A replace battery message is sent to the subscriber email address. In one embodiment, the replace battery message includes a plurality of hypertext link corresponding to a plurality of battery replacement options.

FIGS. 6 & 7 are a flow chart of the steps used in a remote battery replacement notification method in accordance with one embodiment of the invention. The process starts, step 170, by periodically polling a subscriber unit for a battery state by a communication system at step 172. A response including a battery state is received at step 174. When the battery state does not indicate that a battery requires replacing at step 176, the process starts over. When the battery state indicates that the battery requires replacing, a replace battery message is sent to a compact service node at step 178. At step 180 it is determined when a subscriber has finished dialing a called number. When the subscriber has finished dialing the called number, the subscriber is provided with a plurality of battery replacement options at step 182. A response is received from the subscriber at step 184. When the response is to purchase a new battery at a designated store, a battery discount is generated for inclusion in a subscriber bill at step 186. In one embodiment the battery discount is a coupon. At step 188 a report is transmitted to a billing system to remind the customer to change a battery which ends the process at step 190.

Thus there has been described a system and method for remote battery replacement notification that automatically warns a customer to replace a battery. A follow up reminder in the subscriber's bill should make it rare that subscriber will lose their telecommunication services during a power outage.
